I have had a problem similar to the one exposed in this thread. I used to receive rejected messages like this:
"/var/spool/mail/web1_fyc" procmail: Quota exceeded while writing
I followed Tillīs suggestions by increasing the qouta of the user. This strategy worked but not for so long. Rapidly the system reported me that my qouta was reached again. I canīt keep going up in the size of the qouta. I donīt understand why the qouta is being reached if I used to clean my mailbox every 5 minutes and I have not used this user to put information in the site.
Can you tell me how can I clean up the disk usage of the user ?
